Renesas Electronics (TSE:6723) has pushed deeper into Gallium Nitride power devices with a new 100V GaN FET family aimed at AI data centers, humanoid robotics and industrial motor drives.

Recent trading tells a mixed story. The share price is up 36.99% year to date to ¥3,048, while the past 90 days show a 20.25% decline in share price return as enthusiasm cools after a strong run. Even so, a 60.67% one year total shareholder return alongside a 127.59% five year total shareholder return suggests longer term holders in Renesas Electronics have been rewarded, as product launches like the GaN expansion keep attention on the investment case.

Scan hand-picked peers riding the same GaN and AI infrastructure wave as Renesas Electronics by reviewing the 55 AI infrastructure stocks, which is shaping tomorrow's high-efficiency data and power systems.

Renesas Electronics now trades below both intrinsic value estimates and analyst targets after that sharp pullback. Is this a cautious market calling the cycle correctly, or mispricing a still evolving GaN and AI power story?

Most Popular Narrative: 40% Undervalued

Renesas Electronics closed at ¥3,048, compared with a narrative fair value estimate of ¥5,057.69. This frames the recent pullback as a potential disconnect between price and the AI power story the company is building toward.

The build out of GaN based power devices for high voltage AI data center architectures, including new 100 V and 650 V products that are already sampling with a plan for mass production in mid 2027, gives Renesas Electronics a product cycle that can drive revenue from next generation accelerator boards and support gross margin mix.

See why 16 investors see Renesas Electronics as 40% undervalued.

Result: Fair Value of ¥5,057.69 (UNDERVALUED)

Still, the thesis around Renesas Electronics can fray if higher R&D and SG&A spending keeps pressuring margins, or if the GaN patent dispute disrupts AI power plans.
